Forgetting averages, amounts, and odd storms in early Dec for the moment...
Just looking at what time is left on the game clock for 2019 winter it is hard to see another storm right now. This pattern of cold, then warm, then rinse with rain, then repeat is not going to cut it.
We seem to have another cold shot coming on deck late next week but that is still iffy, then we warm again, after that we get into post Feb 15th. Then we begin to live on a model and a prayer to beat the odds
